APPARATUS USED IN ELECTROPLATINGL Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed June 11, 1906. Serial a. 321,259.

To all whom it may concern:

Be it known that LALBERT JOSEPH LEA- VER, electrometallurgist, a subject ofthe King Eyot Works, Hammersmith, London, En land, have in vented certain new and useful Improvements in Apparatus used in Electroplating, of which the following is a specification.

It is well known that great advantages are obtained by agitating and circulating the plating solution during the process of electrodeposition, and various methods have been adopted for doing this.

According screw or like propeller a trunk immersed in the solution and extending as nearly to the bottom of the vat as may be desired.

The arrangement is preferably as follows: The trunk is bent through about a right angle, the horizontal branch of it in which the propeller is placed being normally near the surface of the. solution; but means are provided by which its depth can be varied. If it is desired to aerate the solution, the trunk is raised until the propeller is partly above the surface. The trunk is sup orted b a frame carrying the bearings oft e propel ershaft, which passes into the trunk through a hole near its top. The frame is pivoted to a platform secured to the, vat by a clamp or other suitable device. This platform su ports an electric motor or other suitab f means for driving the propeller-shaft through a universal joint or flexible connection or otherwise.

Figure l-is of an apparatus constructed according to this invention; and Fig. 2 is a'perspective view of the a paratus in use.

a is the si e of the vat, and bis a platform fixed to it.

to this lnvention employ a an elevation, partly in section,

g is an electric motor carried by the frame 0 and driving the shaft f What I claim is- 1. The combination of a vat, a trunk supported in the vat at a distance above the bottom of the vat, a screwropeller in the trunk and means for driving t e screw-propeller.

2. The combination of aivat, a trunk bent through a right angle, the lower side of the angle being approxlmately vertical and the upper side approximately horizontal; means for supporting the trunk above the bottom of the vat, a screw ropeller in the trunk and means for driving t e screw-propeller.

3. The combination of a vat, a frame supported on the edge of the vat, a trunk sup ported by the frame at a distance above t e ottom of the vat, a screw-propeller inthe trunk and a motor carried by the frame and drivin the screw-propeller.

4. he combination of a vat, a frame supported on the edge of through a right angle supported by the frame the lower side of the angle being approximately vertical and the upper side ap proximately horizontal, a screw-propeller 1n the trunk and a motor carried by the frame and driving the screw-pro eller.

5. The combination 0 a vat, a frame hinged to the edge of the vat, a trunk suported by the frame at a distance above the ottom of the vat, a screw-propeller in the trunk and a motor carried by the frame and drivin the screw-propeller.

6. The combination of a vat, a frame hinged to the edge of the vat, a trunk bent through a right angle supported by the frame, the lower side of the angle bein approximately vertical and the upper'si e approximately horizontal, a screw-propeller 1n the trunk and a motor carried by the frame and driving the screw-propeller.
